Atletico have the advantage of an away goal from the first leg, with playmaker Diego scoring a wonder goal, before Neymar equalised for Barcelona with a cracker of his own.

Barcelona will head into the second leg knowing they need to score at least once to have any chance of staying in this season's Champions League, something which will be easier said than done, considering Atletico's home record in terms of conceding goals.

"I don't like to predict what the result might be," Barcelona manager Gerardo Martino said. "What we need to do is to play better than Atletico and to win the game. These teams know each other very well, and they play with completely different styles.

"All I know is that Barcelona haven't gone ahead in any of the meetings this season. We need to see if we can do that and to try to control the match. Atletico are not the type of team who will allow us to control the game for the entire 90 minutes, but we'll try to do that as it is how we like to play. 

"The games between the sides have been very even, though we have tended to be superior in the second halves. It won't be easy but if we try to control the game, and score first, then maybe the outcome will be different."

Diego Simeone has done wonders with this Atletico side, who are currently a point clear of Barcelona in the top of the La Liga at the moment, since taking over as manager, and nothing will please the Argentine more than to take his team to the semifinals of the Champions League.

"This will be a passionate game -- one of the biggest in the UEFA Champions League -- between two teams with different styles," he said. "The result [of the first leg] doesn't mean anything. Barcelona always play offensively and this is a perfect match for them with [possibly] 120 minutes to play.

"We are going to come up against the best Barcelona players of recent times. These games are special for them and they are used to playing them."

Team news: Atletico Madrid: Diego Costa is a major doubt with a thigh injury he picked up in the first leg, and Simeone insisted the talismanic attacker will play from minute one only if he is passed 100 percent fit. "If Diego Costa is fit, he plays. If he is a little less than 100 percent, he will be on the bench," Simeone said. "Otherwise he'll be out. "We will have a look at [him] in training.

"If he doesn't make it, Adrian Lopez will play - if Adrian plays, I'm sure he will have a great game for us." Influential playmaker Arda Turan, though, has been definitely ruled out with a groin injury, but Javi Anquilo could make a return from a neck problem.

Barcelona: Gerard Pique and Victor Valdes are sidelined along with Isaac Cuenca and Jonathan Dos Santos. Carles Puyol, though, has been included in the squad, even though the player is still waiting for the all-clear to plat after a long-term knee injury.

Expected lineups: Atletico Madrid: Courtois; Juanfran, Miranda, Godin, Filipe Luis; Koke, Tiago, Gabi, Diego; Adrian, Villa.

Barcelona: Pinto; Alves, Bartra, Mascherano, Alba; Xavi, Busquets, Iniesta; Fabregas, Messi, Neymar.
